Using an interference technique, the refractive index of both H(2)O and CO(2) films was determined at visible near ir wavelengths as gases were being condensed on a liquid nitrogen cooled surface. For these same films, density also measured. The results for wavelength 0.589 microm 1.26 +/- 0.01 1.43 films. 0.81 0.02 g/cm(3), it 1.67 0.03 g/cm(3).

In 1964, exploration drilling in the German Sector of North Sea hit a gas pocket at ∼2900 m depth below seafloor and triggered blowout, which formed 550 m-wide up to 38 deep crater now known as Figge Maar. Although craters by fluid flow are very common structures, little is about their formation dynamics. Here, we present 2D reflection seismic, sediment echosounder, multibeam echosounder data from three geoscientific surveys Maar blowout crater, used reconstruct its formation. Reflection...
Abstract Hydrocarbon exploration in the North Sea Basin has revealed a multitude of focused fluid conduits, which manifest seismic data as pipe or chimney structures that some instances are connected to underlying hydrocarbon reservoirs. 3D from eastern margin East Shetland Platform reveal presence more than 450 conduits. Most these initiate at Base Tertiary Unconformity and cross-cut overlying sediments. The conduits correlate with intra-platform basin beneath permeable sediment lobes,...
Fault permeability prediction typically relies on empirical relationships between and clay content or burial depth. Calibration of such methods either core data subsurface observations fluid pressure hydrocarbon contact offsets across faults. Published suggest that no exist host rock fault for phyllosilicate-framework rocks, whereas published calibration otherwise. We here present a new method permeabilities to data. This approach is an analogue from electrical engineering compute all major...
Summary Calibration of fault rock seals is based on subsurface buoyancy pressure differences or laboratory measurements. However, overpressure in the are an additional piece information that not used for seal calibration so far, to our knowledge. The similarities between Ohm's (electricity) and Darcy's law enable sealing using overpressure. This method requires 1. An (water) in- output, 2. A reservoir network with fluid compartments connected by juxtapositions but hydraulically separated...
Summary We often can't know if fault sealing is static (controlled by capillary entry pressures) or dynamic the difference between supply and discharge of hydrocarbons), but tend to work as we that static. here examine (a) conditions for hydrocarbons, (b) when can be reasonably confident in our assessment mechanism, (c) anticipated practical consequences incorrect process identification, (d) a suggested exploration strategy mechanism unknown dynamic. suggest controlling factors two...
